I have used them and i cost me dearly. They ****** up my roof of my car because of carelessness bringing it out of the dip tank. I had to buy another car from Arizona for the parts $1800 + shipping + body work. It ended up costing me more to fix their **** ups than I paid. I would NOT recomend them to anyone. Their are other reputable (insured) e coating companies out their. If you do use them ask for a bond and proof of insurance. Also make sure you have a signed agreement and before pictures signed by both parties. With my experience I would tell you to use someone else.
Good Luck on your project,
